What was the reasoning / resolution of the POP forward/backward beam? Are we going to have the right beam for DRMI locking?
|
From Koji's email to me:
"With the backward beam you can see the returning beam even when the PRM is misaligned. That's the only difference. Once the PRM is aligned both beams have the same information."
So, we should be fine. |
